Timeline: summer between P/F/I's sophomore and junior years of college; Vanessa is two years into grad school. Phineas and Isabella are 20; Ferb is 19, Vanessa is 25.
Ferb looked around the room and realized it was time. The hotel ballroom was crowded with tables, full of the friends and families of the Fletcher-Flynn and Garcia-Shapiro families. He sat at the head table between Isabella and Vanessa, a clever bit of seating arrangement on Isabella's part that (among other things) sat him next to his actual girlfriend (the second bridesmaid) instead of his ex-girlfriend Gretchen (the maid of honor, seated on the far side of Phineas). Everyone had been served champagne or sparkling cider according to their age, so he clinked his glass to get everyone's attention as he stood up. This was his final responsibility today, and he was quite glad about that.
Isabella and Candace had spent the last month planning every detail they could; they'd all spent the past week in Danville during the final preparation, and Phineas had increasingly resembled a trapped rat as the formalities wrapped around him. Ferb had almost suggested eloping, but the big princess wedding had been so important to Isabella that he didn't dare tempt his brother with that forbidden thought.
He glanced quickly at his notes, then began his speech. "This is a day that we've all been awaiting for a long time. Some of us longer than others," he said with a smile at Isabella, who smirked in response. She hadn't seen his speech ahead of time, leaving this as the one thing all day she hadn't been in charge of planning; she hadn't been particularly thrilled about anything having that distinction, but had finally been convinced to trust his judgement, if only because he'd flat-out refused to give her any advance peeks at the speech.
Ferb continued. "Today, we celebrate the wedding of Phineas and Isabella Garcia-Flynn, a couple who, if they were any more perfect for each other, you'd swear they were fictional characters. Oscar Wilde said that marriage is the triumph of imagination over intelligence, but this particular marriage is a triumph of both. It has been my privilege and pleasure to call myself Phineas's brother for the past eighteen years, and to call Isabella my neighbor and my friend for the past eleven. And in all that time, they have been two of the most intelligent, imaginative, creative, and inspiring people I have ever met.
"While I was preparing this speech, Isabella's father told me that, on the day Isabella first met Phineas, she told her parents she was going to marry him. Given the accuracy of that prediction: Mr. Garcia-Shapiro, if she gave you any stock tips that day, I hope you were able to take advantage of them.
"That said, what nobody has been told before today is Phineas's reaction to that meeting."
Phineas winced and put his head in his hands. Isabella looked at him, concerned, and then eyed Ferb suspiciously. Ferb took the opportunity to take a sip of water.
"Phineas was, after all, an eight-year-old boy. Girls weren't really on his radar yet in general, and so he didn't seem to pick up on her feelings toward him.
"However, while Phineas hadn't noticed Isabella's feelings yet, I had. Subtlety was not her strong point. And so, as we lay in our beds that night, I asked him what he thought of our new neighbor.
"He said that her Fireside Girls patches sounded 'neat', and he was looking forward to helping her earn them. Now, that doesn't sound unusual to any of you, perhaps, but this was the first time I'd ever heard Phineas willingly offer to do something that wasn't an idea he'd come up with on his own. He tended to be a little single-minded at the time.
"The conclusion seemed plain to me - my brother was developing some sort of feelings for this new girl. So I asked the obvious question: 'Phineas, do you like her?'
"And I was rewarded by something that I had never, ever encountered before, and have very rarely seen since: Phineas Flynn rendered completely speechless."
Scattered laughter came from the crowd. Phineas was trying to glare at Ferb, but couldn't help but smile at the same time.
"He spluttered for a couple minutes, and then confessed that, indeed, he considered her a very interesting person that he'd like to spend more time with. And he thought they could be good friends. But, you know, he didn't like her. She was a girl. And he told me that if I ever told anyone - especially Isabella - about this, he'd take it out of my hide.
"Phineas - I hope you'll forgive me, but I think at this point, we've all figured out that you like Isabella."
Ferb picked up his glass as the wedding guests laughed and Phineas blushed. Isabella was smiling and shaking her head.
"So: a toast to the happy couple. To six years of friendship, and five years of dating, and a lifetime of happiness together. To Phineas and Isabella."
The toast completed, Ferb sat down. He was officially off the hook and, barring anything truly unexpected, unable to mess up Isabella's Perfect Wedding Day.
So, I hadn't planned to write this. I was working on a Ferbnessa story set shortly after this, and I needed to set the scene a bit, and the scene I did it in didn't work. There was far too much 'telling' and not enough 'showing'. So I decided to back up to the wedding, and this scene happened. And I love it. You'll get the Ferbnessa bit tomorrow, if I can fix the ending so I like it.
I envision Isabella as being a bit of a bridezilla, as you can see. I had originally planned to knock some of the corners off of that in Something Special, but for various reasons it didn't happen.
